Double Head Hydraulic Tube Bending Machine
Product Description
1. Overview
It is composed by the material guide frame, bending device, discharge device, mandrel device, electrical system, pneumatic system components. Action cycle is as below:
Manual fix length of straight pipe material in place → pipe clamping → spray oil mist and bending → mandrel exit → pipe clamp loose → discharge → discharge reset (while manual reclaim) → bending reset.
2. Material Guide Frame Device

2.2 Guide frame pin hole positioning, easy installation without adjustment.
2.3 The guide frame is adjustable to accommodate different sizes of elbows.
3. Bending Device
3.1 Driven by hydraulic cylinder, through the gear tooth transition mechanism for bending.
3.2 When bending, the oil mist lubrication function works, can extend the service life of bending mold while improving the quality of the elbow.
3.3 The overall bending mold seat integrated processing, high precision and high precision.
3.4 The support mould and clamping mold are controlled by pneumatic cylinder.
3.5 Bending mold, clamping mold, and the supporting mould are use of alloy steel alloy material by the overall quenching by the CNC equipment precision machining, anti-wear, high precision.
4. Discharge Device
4.1 Discharge by the servo control return pipe to achieve the discharging.
4.2 Simple structure, easy for operation.
5. Mandrel Device
5.1 The return mandrel is controlled by pneumatic cylinder.
5.2 The mandrel rod support plate is hinged and automatically separated when sliding.
5.3 The mandrel rod length can be adjusted for each.
6. Electrical System
6.1 Electrical box is built-in type, operating box is hang type.
6.2 Machine is controlled by PLC, man-machine interface, servo motor and related electrical components, easy and efficient operation.
7. Hydraulic System
7.1 Separated hydraulic station.
7.2 Hydraulic pressure: 6MPa(±10%)
8. Pneumatic System
